What is the Least Common Multiple of 1006 and 1016?

Least common multiple or lowest common denominator (lcd) can be calculated in two way; with the LCM formula calculation of greatest common factor (GCF), or multiplying the prime factors with the highest exponent factor.

Least Common Multiple of 1006 and 1016 with GCF Formula

The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 1006 and 1016, than apply into the LCM equation.

GCF(1006,1016) = 2
LCM(1006,1016) = ( 1006 × 1016) / 2
LCM(1006,1016) = 1022096 / 2
LCM(1006,1016) = 511048

Least Common Multiple (LCM) of 1006 and 1016 with Primes

Least common multiple can be found by multiplying the highest exponent prime factors of 1006 and 1016. First we will calculate the prime factors of 1006 and 1016.
